The strongest *1 smartphone with extreme durability and a tough design *2 capable of clearing 21 types of tests!

This smartphone is compliant with 21 durability standards comprised of 19 MIL-STD-810G durability tests defined by the US Department of Defense and the two sea water resistance and load bearing tests defined by Kyocera.
Furthermore, it's high robustness easily cleared drop tests where the smartphone was dropped from a height of 1.8 m onto iron plates and concrete.

  1. The first au smartphone that is compliant with 19 testing standards of the US Department of Defense (MIL-STD-810G) and clears two Kyocera-defined durability test standards, which includes a drop test from1.8 m high (As of May 10, 2017 examined by Kyocera).
  2. There is no guarantee of being impervious to damages.


Conducted tests that comply with 19 testing standards of the US Department of Defense (MIL-STD-810G) [Blowing Rain, Immersion, Rain Drip, Sand and Dust, Shock, Vibration, Solar Radiation, Humidity, High Temperature, Low Temperature, Temperature Shock, Low Pressure, Salt Fog, Freeze-Thaw, Icing/Freezing Rain]. The performance of this product is checked under the conditions of the testing environment and does not constitute a guarantee for operation for every condition of actual use. Also, there is no guarantee of being impervious to damages or malfunctions.


[Impact resistance]

Conducted tests compliant with MIL-STD-810G Method 516.7-Shock ProcedureIV, as well as a Kyocera-original drop test in which the product was dropped in 26 different orientations onto iron plates and concrete from a height of 1.8m. There is no guarantee against every shock.


[Water resistance]

IPX5 rating: The unit will retain its functionality as a phone even if blasted with water projected at all angles through 6.3 mm nozzles at a flow rate of approximately 12.5 liters per minute for more than 3 minutes from a distance of approximately 3 meters. IPX8rating: Water will not leak inside and the unit will retain its functionality as a phone even if it is gently immersed in a tank of still tap water at room temperature at a depth of 1.5 meters and placed on the bottom for approximately 30 minutes.


[Dust resistance]

IP6X rating: The unit is protected to a point where test dust (a diameter of 75 µm or less) will not enter the unit even if the unit is churned for 8 hours inside a dust resistance testing tube.


[Load resistance]

Kyocera-defined durability test implemented. This means that functionality as a mobile phone is retained even if the body of the device is subjected to a surface load equivalent to 100kgf.


[Salt water resistance]

Kyocera-defined durability test implemented in seawater equivalent to that of the Japan costal area.Water will not leak inside the unit even if immersed for 30 minutes in a depth of 1.5m and functionality as a mobile phone is retained.There is no guarantee of being absolutely durable against seawater.

  • Impact resistance performance is assumed to be that for daily use. Note that the device may break if subjected to extreme impact such as throwing the device or dropping it in an excessive manner. Also, the device may become damaged from impact by dropping even if there is no abnormality in the impact resistance performance.
